MACHINE AND PROCESS FOR BLOWING ORCLEAN'ING- Specification of Letters Patent No. 2,842, dated November 11 842.

To all whom it may concern:

Be it known that I, JOHN W. COCHBAN, of New York, N. Y., have invented an Iniprovement in Machines and Processes for Blowing or Cleaning Furs, of which the following is a specification.

In the drawings hereto annexed which are to be taken as a part of this specification, Figure 1, is the top of the-machine,

Fig. 2, an outside view of the front of the machine with the doors closed.' Figs. 3* and at, the ends, Fig. 5, an inside view of the front of the machine with the doors taken off, Fig. 6,'the inner section or side of the. rece1ver, showing an opening covered with wire cloth. Fig. 7, a View of the wheelhouse and the space between the'receiver and the flue apartment, Fig. 8, an inside view of the flue apartment. v

The machine is divided as follows C, an apartment called the receiver; .G, the space between the receiver and the flue apartment containing the Wheelhouse and theblower,

and H, the apartment containing the lines, which are placed one above the other, and are connected with'each other by leaving aspace open at the alternate end of each division, as shown in Fig. 5; E, are openings, one at each end of the blower, through which the fur is drawn in by the action of the blower and carriedvby the current of air formed by it to and frothrough the tines,

entering at A Fig. 5, and issuing out and falling into the receiver at B and there retained while the air escapes through an opening, D, Fig. 7, in the inner side of the receiver, which is covered with wire cloth.

The bottom of each flue is coated with tar or any glutinous or adhesive substance and kept wet with water, and the fines are then prepared for operation by passing through them a quantity of pure hair, which by adhering to the bottom forms the coating necessary to catch and retain the hair and thus separate it from the fur which passes through into the receiver. Water 1. The obtaining on this plan a passage 7 way or fur-duct of sufficient length to per- 7 fectjthe separation of the hair from the fur alone is sufficient for this purpose and is only obj ectionablebecause of its drying too soon. By this improvement it can be applied at all times in a fewm'oments by opening-the doors or rBIIlOving. the front of the flue apartment and a sufiicient degree ofmoisture kept up continually.

The flues aresix inches deepand inches wide, but their dimensions may be varied as may be found advisable, and the length ,of the passage way or" fur-duct through them may be from three hundred ,to five hundred feet and upward according.

to the size and power of the blower ,'which ordinarily may be about thirty two inches in diameter and sixteen inches in width, but

these dimensions may be varied to meet'the convenience of the operator.

The invention or improvement claimed in one operation andtlie extension of it to any required length in an ordinary sized room by increasing the number and length of the fines.

2. The process of coating the flues by the 7 use of water as well as any adhesive sub stanceto-catch and retain the hair as herein before described, instead of the cloth covering now generally used for that purpose, the value of this part of the improvement being the facility with which the coating is obtained and the saving of time and labor.

3. And lastly, that by the draft or suction caused by the blower the fur can be drawn through the openings at, E Fig. 2 (or some other convenient place) direct from the breaker or cutting machine into the wheel house by means of a fine or conductor.
